The Magnetometer Array for Cusp and Cleft Studies (MACCS) program
operates magnetometers in the arctic to study the near-Earth space
environment.

Dear MACCS Users,

Our servers are currently partially down for maintenance, and so only data from
2011 through the current time is available. We anticipate that our historical
data (1992 through 2010) will be available again
before the end of 2017.
